Magnetic MagSafe Filter Holder JJC MFS-II for 67mm Filters — compatible with iPhone

JJC MFS-II is a magnetic MagSafe-style filter holder designed to attach 67mm photographic screw-in filters to MagSafe-compatible iPhones and cases. The compact adapter uses a magnetic mounting system to align and hold the holder on a phone back or MagSafe case, while providing a threaded receptacle for standard 67mm filters. It enables quick attachment of neutral density, circular polarizer or color correction filters to the phone camera optical path, expanding control over exposure, reflections and color balance for mobile photography and videography.

Advantages

The magnetic mounting mechanism provides fast, repeatable attachment and removal without adhesives or clamps. Accepting 67mm screw-in filters gives access to a wide range of photographic optics from neutral density to polarizers and color filters, retaining the original filter threading for secure and precise alignment. The low-profile design keeps the holder close to the phone to minimise vignetting and maintains compatibility with multiple MagSafe-compatible cases and backs.

Suitable for

• Mobile photographers who use dedicated 67mm filters on iPhone cameras
• Videographers needing consistent neutral density control when shooting outdoors
• Creators who require polarization to reduce reflections on water or glass
• Color grading or white balance adjustment with screw-in color correction filters

Key specifications

• Mounting: Magnetic MagSafe-style attachment for compatible phone backs and cases
• Filter thread: Accepts 67mm screw-in photographic filters
• Compatibility: Designed for iPhone models and cases that support MagSafe alignment
• Material and finish: Durable construction to maintain alignment and support filter weight
• Profile: Low-profile design to reduce vignetting on wide-angle smartphone lenses

How to use

Align the magnetic face of the JJC MFS-II holder with the MagSafe area on the iPhone or MagSafe-compatible case; the magnets will secure the holder in place. Screw a 67mm filter into the holder’s threaded opening until it is seated and aligned. Check the camera framing for vignetting or rotation and adjust the filter orientation if needed—rotate polarizers to achieve the desired reduction of reflections. Remove the filter by unscrewing it and detach the holder by lifting it away from the phone when finished.

Usage recommendations

For best results, use high-quality 67mm photographic filters suited to the task (ND, CPL, or color correction). Ensure the phone and holder surfaces are clean before mounting to maintain strong magnetic contact. When using heavy or stacked filters, verify secure seating and test for vignetting at your intended focal length; remove additional cases or use a slimmer MagSafe-compatible case if necessary.
